From the photographer: "The one day old crescent moon
is visible above one of the ancient watch towers of Anarak city in Esfahan, Iran. Aged over 150 years, this tower is one of the few magnificent towers standing on its own without any reconstructions.
Indicating the starting of months in Arabic calendar, crescent moon has a significant role in Islamic calendar. In old days, Muslims climbed up to these towers to have a clearer view of the horizon in
order to observe the crescent moon and announce the new month or even the new year." - Mahdi Zamani
